A Correct answer
Explanation

Sunrays are focused at a point using concave reflectors. The solar radiations falling on the concave reflectors are focused at a point. Thus, large amount of heat radiations concentrated at a point increases the temperature of that point to a high value. Hence, option (1) is correct.
